Question

我是Android的新手，正在开发演示应用程序，因为我有一个活动在屏幕顶部包含一个编辑文本，并希望在该活动开始时显示键盘我已经尝试了很多方法，但这些都不起作用，任何人都可以帮我整理一下吗？

Answer 1

你必须把注意力放在 EditText.try 上。

android:focusable="true"

在您的编辑文本中，它将打开软键盘。

尝试将清单更改为

android:windowSoftInputMode="stateVisible"

而不是

android:windowSoftInputMode="stateAlwaysVisible" .

如果问题仍然存在，请尝试使用

InputMethodManager imm = (InputMethodManager)getSystemService(
    Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(mEditText, 0);
